			<p><span style="font-family: &quot;Lucida Grande&quot;, 微软雅黑;letter-spacing:1.5px">缓存和算法一样，几乎是所有大厂的敲门砖。对于后端开发来说，算法会影响你是否可以接到 Offer，而你<strong>对缓存知识的理解程度，则会影响你 Offer 的薪资水平</strong>。可以说，对缓存的掌握程度，在某种意义上决定了后端开发者的职业高度。</span></p>

			<p>&nbsp;</p>

			<p><span style="font-family: &quot;Lucida Grande&quot;, 微软雅黑;letter-spacing:1.5px">因为互联网公司基本都是直面用户的业务，要想改善用户体验，就要持续确保系统的访问性能和可用性，而使用缓存最常见且有效的手段。<strong>你要是不懂缓存，就很难写出高性能大并发的代码来满足业务需求</strong>。所以，面试官通常会通过应聘者对缓存相关知识的理解深入程度，来判断其开发经验和学习能力。</span></p>

			<p><span style="font-family: &quot;Lucida Grande&quot;, 微软雅黑;letter-spacing:1.5px"><strong>想要快速系统地学好缓存，还是需要跟真正有丰富实战经验的&ldquo;大佬&rdquo;学</strong>。这里说的&ldquo;大佬&rdquo;，不是说这人名气有多大，是说他的缓存&ldquo;缓存&rdquo;抗过多大的压。比如，刚过去的淘宝双11、春节红包、微博七八个明星并机结婚/离婚&hellip;&hellip; 。经历过这些&ldquo;宕机&rdquo;&ldquo;修复&rdquo;&ldquo;重建&rdquo;再&ldquo;宕机&rdquo;，才配得上「吃透缓存」这四个字。</span></p>

			<p><span style="font-family: &quot;Lucida Grande&quot;, 微软雅黑;letter-spacing:1.5px">最近，微博缓存的元老级人物陈波（网名：fishermen）在拉勾推出了<strong>「 300 分钟吃透分布式缓存」</strong>专栏。</span></p>

			<p><span style="font-family: &quot;Lucida Grande&quot;, 微软雅黑;letter-spacing:1.5px">他在 2008 年加入新浪，最开始是做后端开发的，因为业务需要（微博平台重度依赖缓存）和技术实力被转到了基础架构部研究缓存，算是微博平台最早一批做缓存的人员。</span></p>

			<p>&nbsp;</p>

			<p><span style="font-family: &quot;Lucida Grande&quot;, 微软雅黑;letter-spacing:1.5px">新浪微博的用户规模大家应该都懂：2019 年日活用户超 2亿，每日新发 Feed 1～2亿，历史数据高达千亿级。核心接口可用性要达到 99.99%，响应时间在 10～60ms 以内，核心单个业务的数据访问量高达百万级 QPS。</span></p>
